MACHINE FOR MAR-KING SOLES.

Application filed January 4, 1919.

To all whom it may concern:

Be it known that I, JOHN C. I-IARDIE, a citizen of the United States, residing at Brockton, in the county of Plymouth and State of Massachusetts, have invented certain Improvements in Machines for Marking Soles, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machine for marking parts of boots and shoes to pro vide indications to assist in positioning in proper relation the parts in the shoe. In the illustrative embodiment of the invention herein shown. means is provided for marking the tread face of the innersole of a boot or shoe to indicate the minimum amount of extent of the upper over the bot tom of the innersole.

In the manufacture of McKay shoes it is essential that the upper be lasted over the innersole an amount sufficient to ensure that the means employed for fastening the innersole and the outsole to the shoe will secure a firm hold upon the upper. In order that the inspector shall be able to hold the workmen who perform the lasting operations up to a certain standard in this respect, it is desirable to provide upon the bottom of the innersole a mark which will show how far it is necessary that the upper should extend over the margin of the innersole. If, in the lasting operation, this mark is covered by the upper, the workman may be sure that his work will pass inspection and, on the other hand, the inspector may readily ascertain that the lasting operation has been properly done. An object of this invention is to provide a machine for making a suitable mark or indication on the innersole at a predetermined distance from the edge of the inner sole.

A feature of the invention consists in an organization including a guide against which the sole is placed and along which it may be moved and means for marking the sole at a predetermined distance from the guiding means. Preferably the marking means is operated relatively to the sole, and it may, as, herein shown, be mounted on a rotating member which causes the marking means to act on the surface of the mar- Serial No. 269,628.

gin of the sole over a predetermined width of that margin.

Another feature of the invention consists in a yielding rest arranged to engage the face of the sole opposite the face which is being marked. and arranged to ensure proper pressure of the sole against the marking means.

In order to save time, it is desirable that the operation of so marking the sole be performed simultaneously with another operation on the sole. In the illustrated construction there is provided means for performing a cutting operation upon the sole and means for effecting a marking operation upon the sole. Preferably and as illustrated, the marking mechanism is combined with mechanism for beveling or chamfering the inner corner of the edge face of the sole which operation is frequently performed upon the innersole to ensure that said edge will not cause discomfort to the wearers foot in case it should come in contact therewith.

In the construction of the drawings, a rotary chamfering cutter is mounted on a shaft which also carries the marking means, and the same guide which positions the sole for the operation of the marking means also position the sole for the operation of the chamfering cutter. The marking means, as shown, comprise sharp edged rollers mounted upon axes perpendicular to the axis of the shaft and adapted as the shaft is rotated to score, scratch, or otherwise mark or produce a discoloration on the marginal portion of the sole at a pre determined distance inwardly from the edge of the sole.

In the drawings,-

F ig. 1 is a front elevation of the head of i the machine;

Fig. 2 is a perspective'detail of the marking rolls and the member on which they are mounted; and

Fig. 3 is a view of the bottom of a sole having portions of its margin marked by the machine.

. In the drawings, the numeral 2 indicates the head of the machine embodying the present invention. Journaled in the head 2 is a shaft 4 having at its outer end a smallfrusto-c'onical cutter 6. Inwardly of the cutter 6 is a smooth guide 8 for the edge face of the sole which may be formed a cylindrical portion rotating with the shaft. gurrounding the guide 8 is a member 10 which is held by a set screw 11 to the guide 8 and upon which it is adjustable to vary the width of the guide. The member 10 rotates with the shaft and has a frusto-eonical face 12- which serves as a gage for the bottom face of the sole whose edge is presented to the guide 8 and cutter 6. Notches 14: are formed in the marginal portions of the member 10 and in these, notches are mounted marking means 16 which engage the bottom face of thesole. As herein shown the marking means consist of sharp edged rolls mounted upon screws 18. The screws form rates for the marking rolls which axes are arranged at right angles to the axis of the shaft 4:. All of the markers 16 are arranged at the same predetermined distance radially of the shaft from the guide 8 which distance is the same as the width of the margin of the sole which is to be marked.

A bracket 20 is fixed by a screw 2i to a part 22 mounted upon the machine head and at its lower end carries a rest arranged to engage the inner face of the sole when presented'to the machine for its operation. The rest comprises a hemispherical end portion 24: for engaging the sole and a stem 26 which passes loosely through the bracket 20 and is provided at its outer end with a nut 30 and a lock nut 32. Surrounding the stem 26 is a spring 34 which presses the res 524itoward the sole as far as permitted by the nut 30 and applies sufficient yielding pressure to the sole to ensure the proper operation of the marking means 16 upon it.

In the operation of the machine the members 4, 6, 8 and 12 are rotated at very high speed. A sole is presented to the machine with its edge face against the cylindrical guide 8 and its inner face against the rest 2st and is moved rapidly longitudinally along the guide 8, the cutter 6 acting to chamfer the inner corner of the edge race of the sole and the marking rolls 16 acting upon the marginal portion of the opposite or bottom face of the sole and forming upon that face of the sole a well defined line A.

at a predetermined distance from the edge of the sole, as shown in Fig. 3, which line is used in the lasting operation to show the workman the minimum amount which the upper should extend over the innersole bottom.

The paths followed by the marking means as they successively traverse the -margin of the sole inwardly and outwardly relatively thereto, are indicated by lines in Fig. 3. It. will be noted that the direction of move ment of the markers at their points of farthest advance inwardly of the sole, as at A, coincides with the direction of movement of the sole and that successive markers act repeatedly along a line joining these points.

At other portions of the path of traverse the successive lines made by the markers do not coincide but are either nearly parallel, as at B, or intersect at a substantial angle, as at C. The movement of the sole relatively to the markers during their contact with the sole causes the marks made thereby to be blurred except at those portions where the direction of movement of the markers coincides with the direction of movement of the sole so that the resulting effect of the markers is to form a visible change in-the appearance of the margin of the sole which is most pronounced at the inner edge of the margin where a well and shades out toward the outer edge of the margin. It is, of course, desirable to e);- tend the marking at least around the sides and forepart of the sole. In Fig. 3, for convenience, the showing of the marked margin is fragmentary.

Having thus described my invention, what- I claim as new and desire to secure by Letters Patent of the United States is: I

1. In a machine of the class described, the combination of a sole edge guide, means for operating upon a face of the sole engaging said guide to mark said face parallel to and at a predetermined distance from the sole edge with a clearly defined area. of demarcation extending from the marginal edge to the inner portion of the sole, a. rest engaging the untreated face of the sole, and resilient means acting upon the rest to cause it to hold the sole in marking relation to the marking means.

.2'. In a machine of the class described, the combination of a rotary guide for the edge face of a shoe sole, and moving means actuated by said guide for acting on the entire margin of the face of the sole and relatively thereto for producing mechanically a disdefined line is formed coloration of said margin to distinguish it from the rest of the sole.

8. In a machine of the class described, the combination of aguide for the edge face of a. sole, and means having an operative movement relatively to the sole transversely and longitudinally of its edge for repeat edly marking the entire marginal area of the sole for a predetermined distance from the edge face of the sole, said longitudinal movement occurring solely at the inner por' tion of said margin.

4. In a machine of the class described, the combination of a guide for the edgefaceof a sole, marking means rotatable relatively to the sole about a center located beyond said guide so that said marking means 'will traverse the sole margin from itsouter edge inwardly of the margin and then outwardly of the margin, and means for causing the marking means to traverse said sole margin in such rapid succession that the appearance of the margin is changed over a predetermined area and a line produced. which is most well defined at the inner limit of the margin.

5. In a machine of the class. described, the combination of a guide for the edge face of a sole, a cutter for chamfe-ring a corner of the edge face of the sole, and means for effecting upon the entire margin of another face of the sole a visible change producing a well defined line at a predetermined distance from its edge face.

6. In a machine of the class described, the combination of a guide for the edge face of an unattached innersole, and a. plurality of knife edges operated relatively to the sole while in contact therewith for effecting upon the bot-tom face of the sole a change in the appearance of the entire outer portion of the sole surface such as to produce a well defined line at a predetermined distance from the edge of the sole to aid in overlasting the upper and without materially altering thesurface engaged by the overlasted upper.

'7. In a machine of the class described, the combination of guide to receive the edge face of a shoe part, and marking means having a marking edge moving relatively to the shoe part in a circle, an arc of which extends from the edge face of the part over another face of the part a predetermined distance from the position of the edge face as determined by the guide.

8. In a machine of the class described, the combination of a guide for the edge face of a sole along which the sole is moved for the operation of the machine upon it, marking means operated to traverse the sole margin in a path less than a semi-circle, and means for causing the marking means to traverse said sole margin repeatedly in such rapid succession that the appearance of the niar gin is changed over an area extending a predetermined distance from the sole edge inwardly. V

9. In a machine of the class described, the combination of a rotating guide for the ed e face of a sole, means actuated by the guide relatively to the sole for marking the face of the sole, and a yielding rest for maintaining the sole face in contact with the marking 111631113- 10. In amachine of the class described, the combination of'a guide for the edge face of a sole, and a scoring roll actuated relatively to the sole to form upon the face of the sole a line at a predetermined distance from the margin.

11. In a machine of the class described, the combination of a cylindrical rest for the edge of a sole, a series of scoring members arranged at predetermineddistances radially from said rest and adapted to act upon another face of a sole, whose edge face is held against said rest and moved longitudinally relatively to the rest, to form a distinguishing area on said sole face with a well defined inner marginal line.

In testimony whereof I have signed my name to this specification.
